For smokers, the lung is a target for constant irritation of tars and chemical agents from cigarette smoke which may result in the development of lung cancer, here shown by the whitish area in an otherwise blackened lung. | |
|
For nonsmokers, here is a inflated, essentially normal lung to compare to the above smokers lung. | |
|
This is an enlarged, inflated emphysemateous lung. It fills the lung cage of the chest and at the same time has little ability to exchange oxygen and carbon dioxide. |
| As a doctor views the voice box, here he sees that one vocal cord has been completely destroyed by cancer. The other vocal cord shows signs of advanced invasion and will soon disintegrate. |  |
| The inner wall of the healthy artery (left), shows branches leading off from the main blood vessel. Note the smooth surface and lack of cholesterol deposit. There are two arteries in the right picture. The upper is from a 32 year old high fat eater, the lower from a 34 year old low fat eater. Note the cholesterol deposits in the inner wall of the upper picture. Evidence indicates that nicotine increases the cholesterol deposit. |
